To all lwhom it may concern:

Be it known'that I, WILLIAM J. S'rooP,

a citizen of the United ,Statesv of America,-

and resident of Wheeling,"county of Ohio, and State of West Virginia, have invented certain new j and useful Improvements in Apparatus for Handling Metal Plates and Sheets, of which the following is a speciication.

This invention relatesbroadly to an apparatus4 for handling metal plates and L sheets, and moreparticularly to improved means for effecting the transfer of` plates and sheets from the finishing rolls of a rolling mill to the shears.

The primary object provide a conveyer-` to which the heated plates and sheets which emerge from' the iinishing rolls of a mill or mills 'may be delivered and by vwhich such Iplatesr sheets will be transferred to a -point in proximity to the shearswith their surfacesfree from scratches, and other injuries to which they are subjected when handled in the heretofore revailing manner. f v

A rther object is to rovide mechanism whereby the plates an sheets are automatically deposited ina position wherein they will be automaticallynicked up bythe emechanism for conveyer and also' to provi receiving plates and sheets from said con-' such lates and veyer and for -eonveyinv a still sheets to the shears. An

promptly performing the work of transferring heavy metal plates and sheets from the finishing rolls to the shears, accom lished by the laborious workl of draggirg t em along the floorl by hand.

ith these' and other important objects in construction, arrangement of/parts and'combinations of mechanical elements which will hereinafterA be fully described,- reference being which l Figure 1 is a top plan view lof the invention, partially broken, illustrating diagrammatically the preferred relative arrangement of the various mechanisms involved.

Fig. 2 is ar partlal invention;

ofthe invention is to rther ob ject 1s to provide mechanical means for heretofore had to the accompanying drawings, in

elevation of Fig. 11 is an enlarged transverse sectional elevation of the cooling mechanism.

Referring to saidv drawings, in which like designating characters distinguish like parts throughout the severall 4views A indicates-generally a conveyer by of which .plates or sheets are conveyed a feed-table B to a delivery table C. feedtable B is located in a position convenient tothe finishing rolls -so that plates or sheets received from the latter may be readily transferredthereto.l As herein shown, said feed table isf`-designed for use in connection withtwo sets 'of finishing rolls D and E, being located'lin front of and intermediate the latter, shown in Fig. 1, so that sheets may be fde'livered to opposite ends thereof ,fromthe adjacent rolls. is'pre'ferably disposed on a level with the floor, as shown :1n Fig. 2, and comprlses three series of rollers b, b and b2, the series b` being located atand adjacent to one end of the table'and being positively driven for carrying sheets deposlted thereon to the intermediate series b2 the rollers of which aredead, or idle. The series b --at and adjacent .to the Vopposite end of the table are also positively driven, but in reversedirection, for conveying sheets deposited thereon means from Said' Said table 1 sheets delivered to said series b2 from either- I end remain stationary until picked up by the conveyer A in a manner which will er inafter be described'. f Said conveyor A, which has' `its receiving nd located adjacent to the position of the ite' idle rollers b2 of the table comprisesa plu-l rality of endless chains, designated generally by the numeral 1, disposed yin parallel relation and carried by sprocket wheels l2 5 mounted upon shafts 3 journaled at oppEosite ends of. a suitable supporting frame 4. ach chain is composed of a plurality ofl links 5 and 6 mounted upon axle-like shafts or pins l7 l.carried by. rollers. 8 which travel forward 10 upon'trackw-ays 9.1nountedupon the top of the frame 4 and return upon trackways 10.

.Thelinks 5 are preferably of elongated substantially oval plate-like form, as shown in Fig. 6,- and the links 6 are ofsimilar form except that each thereof has formed integralv vent'any tendency of .the chain to' over-f` turn.

To provide for fingers 6'EL thereof will always lbe located in transversely alined strai ht rows, shafts 11 36' are located at suitable intervals, the same connecting the various chains and displacinglink-connecting pins of each, as shown in' Figs; 4 and 5. f i. -j Mounted upon the shaft 3 which lies adf jacent to thefeed-table B is a vdisk 12 which 1s peripherally recessed to provide .alternate rounded projections 13 and recesses 14. The

periphery of said disk is engaged by a roller 15 carried by one endV of a lever 40 16wh1ch is pivoted intermediate its ends upon a suitable support, as 17. Pivotally" connected to .the opposite e'nd of 'said lever` 16 is one end of a link 18 which has its op'- posite end pivotally connected to a crank arm 19 carriedby a transverse shaft l20 in 4front of and adjacent to the feed-table. B.

Fixed upon said shaft 20 is a tilt-'table com-v lposed ofa plurality of parallel arms 21 which are relatively spaced apart to be l`50 movable into and out ofpositions between lhl various dead rollers b2l of said feedlimitof their movement to lie orizontally with their rear ends located below the level occupied by plates 1or sheets deposited upon g 'said rollers' b2, .and at thevopposite limit-:of

sheet will be elevated to a substantially upright edgewise position.` Such position will be maintained by the sheet during the'ad- Vance of said conveyer until, in passing over livered thereagainst from the under-'lyingv nozzles of the cooling mechanism.

From the foregoing description it will be understood that the plates or sheets are handled automatically from the moment that they are de osited upon'the live rollers of the feed ta le until they reach the shears; and that, not only is the very heavy labor heretofore involved in draggingl the plates andsheets from'the finishing rolls to the shears wholly eliminated, but such plates and ,sheets are not subjected to the injurious abrasion which results from such dragging. Furthermore, when the cooling mechanism is employed, the sheets are uniformly cooled while being transported.

As is obvious, the conveyer may be em- `Ihlloyed in connection with a single set of ishing rolls, in which case the employi ment of -the long feed tabledescribed may .ble embodyin 4idle rollers,

artable embod ing be dispensed'with; or,

of the fee taonly the dead roller portion ble B may be employed. Further, the de livery table may be dispensed with and plates or sheets delivered directly to the shears. I WhatH is claimed is- 1.. A conveyer prising, in combination'with a receivlng taa tilt-table. embodying aral el arms normali disposed between said rollers and moval le to an inclined position, a'frame havin one end located adjacent `to said tilt-tab e, transverse shafts carried at the opposite ends of said intermediacy of one of said shafts, and meansframe, a plurality of conveyer chains, wheels for carrying'said chains mounted on said shafts, sheetsupportingl carried` by said* chains at spaced intervals, a peri herally recessed` member vrotatable throng the coperating with` said member and having connection with said tilt-table whereby the latter is actuated to move tocand from .its inclined position for delivering sheetsjfrom 4 said 4receiving' table to said chains between said fr'igers.v` f 2.'
